I came across a vehicle (my moms car) that actually has no Bluetooth streaming built into it. It has Bluetooth hands free for when your driving but no A2DP (Advanced Audio Distribution Protocol) support. Well, if your car has an Auxiliary port, this device is for you. It’s called the Anker Soundsync A3352 Bluetooth Receiver (P.S. it’s only $30!).
Below is a closeup of what it actually looks like. You simply plug it into your Aux port and sync your smartphone or MP3 player with it. Most people use smartphones. You can adjust the volume on the unit itself or you can do that on your phone or even on your vehicles stereo!. The crucial part of this device is that you need to keep it charged. Simply buy a cig lighter USB charger and this device comes with a micro USB cable so you can plug it right into the cig lighter charger easily. Anyways, if you want to buy this thing go here. It’s really great for older vehicles that you dont want to modify for Bluetooth.
